Determining the effect of sowing density is crucial for good tillering and production of &nbsp;dry matter yield of green manure crops. An experiment was to determine the effect of sowing density on tiller number, total dry matter yield production and ground cover by green leaf blades of two green manure crops namely winter rye and lolium. Split-plot design was used with a green manure crop as a main factor and sowing density as a sub-plot factor with six blocks in 3 different sowing densities. An advisable sowing density of 50% and 100% did show a significant difference on the number of tillers for winter rye. Sowing density did show a significant linear effect on ground cover by green leaf blades of the crops. Sowing density showed a significant linear effect on total dry matter yield. To evaluate the effect of environment further investigation would be need.&nbsp;

<div>Background: Non-chemical management methods, including cover crops, has an essential role in diminishing weed infestations and reducing the use of herbicides. 
 
Methods: To evaluate the suppressive effects of four cover crop options on weed populations, a field experiment was conducted in factorial randomized bock design with three replications at Ardabil Agricultural and Natural Resources Research Station, Ardabil, Iran, in 2016. The treatments consisted of legumes and cereal cover crop as one factor (Control, Rye, Common vetch, Grass pea and Hungarian vetch) and crop management strategies as a second factor [forage use (FU) and land cover use (LCU)]. 
 
Result: Grass pea sown as fodder use strategy recorded the highest fresh and dry weight of weeds significantly. The greatest potato yield production was observed in Rye and Hungarian vetch plots, approximately 5000 kg ha-1 in both FU and land LCU strategies. Generally, it seems that Rye and Hungarian vetch could be acceptable options to use in potato production as cover crops.&nbsp;&nbsp;</div>
